RAIL HEAD RE-PROFILING MACHINE AND SELF-PROPELLED RAIL HEAD RE-PROFILING DEVICE
PROBLEM TO BE SOLVED: To provide a rail head re-profiling machine and re-profiling device that, in re-profiling a head top surface or corner of a rail head horizontally or with an angle, are capable of performing re-profiling while securely and accurately moving and tilting a rotary grindstone along a shape of a surface of a rail head, with a simple configuration.SOLUTION: A rail head re-profiling machine includes: a vertical direction movement mechanism part 22 that vertically moves a re-profiling machine body 21 by using rotation of a vertical direction movement motor 22a to make the distance between a rotary grindstone 21c and a head of a rail R to be re-profiled be shorter or longer; a grindstone surface angle change mechanism part 23 that rotatably supports the lower part of the re-profiling machine body 21 and moves the upper part of the re-profiling machine body 21 in the longitudinal direction to change an angle of a grindstone surface 21c1 of the rotary grindstone 21c with respect to a surface of the head of the rail R; and a longitudinal direction movement mechanism part 24 that moves the re-profiling machine body 21 in the longitudinal direction, the vertical direction movement mechanism part 22, and a grindstone surface angle change mechanism part 23.SELECTED DRAWING: Figure 16
【課題】レール頭部の頭頂面や角部を水平や角度を付けて削正する際に、簡単な構成で回転式砥石をレールの頭部表面の形状に沿って確実かつ正確に移動および傾斜して削正することができるレール頭部削正機、および削正装置を提供する。【解決手段】上下方向移動用モータ２２ａの回転により削正機本体２１を上下方向に移動させて、回転砥石２１ｃを削正すべきレールＲの頭部に対し近づけたり遠ざける上下方向移動機構部２２と、削正機本体２１の下部を回動可能に支持すると共に、削正機本体２１の上部を左右方向に移動させて、レールＲ頭部の表面に対する回転砥石２１ｃの砥石面２１ｃ１の角度を変える砥石面角度変更機構部２３と、削正機本体２１と上下方向移動機構部２２と砥石面面角度変更機構部２３を左右方向に移動させる左右方向移動機構部２４とを有する。【選択図】図１６
